K'nex Drivetrain

I could improve a lot, like I'm trying to figure out how to make a clutch system, since it's a 2 speed manual. Also I need more parts but that's all for now. ChassisDude98 is the channel who created the V-8 engine, but I tweaked it a little bit. This drivetrain includes an engine, torque converter (doesn't make sense for a manual, I know),a 2 speed manual transmission, the driveshaft, and the differential. If you have any suggestions then leave it in the comments.    • Knex v8  engine instructions
